Question

What do the coefficients of a linear regression line tell you?

Answer 1

`haty= b_0x+b_1`

Explanation:

A simple least square regression line with an independent and dependent variable will have just two coefficients (`b_0 and b_1`)

`b_0` represents the slope of the regression line. For every 1 unit change in the independent variable (x), the dependent variable (`haty`) will change by `b_0` units.

`b_1` represents the y-intercept and may or may not represent valid information. May times, the y-intercept ( when x = 0 ) is simply meaningless.

hope that helps
